Abstract
Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.
Highlights
Energy consumption is rising steadily due to industry and agriculture development as a result of population and economic growth
Extensive studies have been conducted on the principal features of zinc oxide-based composite materials regarding synthesis, development, modification, as well as their application in energy storage systems
A summative view of zinc oxide-based composite materials was presented with specific consideration on the applications in solar cells, batteries, and specific capacitance (SC)
Summary
Energy consumption is rising steadily due to industry and agriculture development as a result of population and economic growth. The natural resources of energy are becoming increasingly rare, and the nonrenewable resources of energy will eventually run out in the future. These energy resources are extensively applied in industries utilizing energy storage technologies. A promising solution to the world’s energy crisis is to replace potent, sustainable, and low-cost.
